 wherein: 
 the display panel comprises: 
 an active area configured to display an image; and 
 an inactive area formed at an edge of the active area, the inactive area being configured not to display an image, 
 the display panel is coupled to the optical plate via a first adhesive member disposed in contact with the inactive area, 
 the optical plate is fixed to the guide panel via a second adhesive member disposed in contact with an area corresponding to the inactive area between the optical plate and the guide panel, and 
 the guide panel comprises: 
 a seating surface facing the optical plate; and 
 a receiving surface formed inwardly of the guide panel from the seating surface and at which the second adhesive member is located. 
 
     
     
       2. The display device of  claim 1 , wherein the guide panel further comprises:
 a vertical surface extending long from the optical plate in a direction toward the frame and to which the seating surface is connected; 
 a coupling surface coupled to the frame; and 
 an inclined surface configured to interconnect the seating surface and the coupling surface, the inclined surface being configured to form an obtuse angle relative to the frame. 
 
     
     
       3. The display device of  claim 2 , wherein
 the optical plate comprises: 
 a glass panel configured to form a core; 
 a first optical sheet located between the glass panel and the display panel, the first optical sheet being coupled to one surface of the glass panel; and 
 a second optical sheet disposed opposite the first optical sheet with respect to the glass panel, the second optical sheet being coupled to the other surface of the glass panel, 
 an area of each of the first optical sheet and the second optical sheet is less than an area of the glass panel, whereby a portion of the glass panel adjacent to the inactive area of the display panel is exposed outside, 
 the first adhesive member is adhered to the display panel and the glass panel, and 
 the second adhesive member is adhered to the receiving surface of the guide panel and the glass panel. 
 
     
     
       4. The display device of  claim 3 , further comprising a reflection sheet, the reflection sheet comprising:
 a first part located on the substrate; and 
 a second part located at the inclined surface of the guide panel. 
 
     
     
       5. The display device of  claim 4 , further comprising a barrier configured to cover a lateral surface of the optical plate adjacent to the first adhesive member and the second adhesive member. 
     
     
       6. The display device of  claim 5 , wherein the barrier comprises a reflective material or an absorptive material. 
     
     
       7. The display device of  claim 6 , wherein
 the receiving surface is formed so as to be lower than the seating surface, a step being formed between the receiving surface and the seating surface. 
 
     
     
       8. The display device of  claim 6 , wherein
 the receiving surface is formed from the seating surface to the vertical surface in an inclined state. 
 
     
     
       9. The display device of  claim 6 , wherein
 the display panel further comprises a sealant configured to cover the inactive area at a lateral surface of the display panel, and 
 a width of each of the inactive area and the sealant is less than a width of an exposed surface of the glass panel with which the second adhesive member is in contact. 
 
     
     
       10. The display device of  claim 9 , wherein
 the optical plate further comprises a side cover formed at a lateral surface of the glass panel adjacent to the first adhesive member, and 
 the side cover comprises an absorptive material or a reflective material. 
 
     
     
       11. The display device of  claim 3 , further comprising:
 a lens configured to cover the light source, the lens being mounted on the substrate; and 
 a reflection sheet located on the substrate, wherein 
 the reflection sheet is located between the substrate and the lens, and 
 a distal end of the reflection sheet is located adjacent to the guide panel. 
 
     
     
       12. The display device of  claim 11 , wherein the lens comprises a support protruding from an upper surface of the lens and extending toward the optical plate. 
     
     
       13. The display device of  claim 12 , wherein the support is adjacent to or in contact with a lower surface of the optical plate. 
     
     
       14. The display device of  claim 1 , wherein the guide panel is fixed to the frame via a fastening member extending through the frame. 
     
     
       15. The display device of  claim 1 , further comprising:
